名前	型	方向	説明
InfHandle	void*	in	対象の開いているINFハンドル。
InfContext	INFCONTEXT*	inoptional	対象行を示すINFCONTEXT構造体へのポインタ。NULLでFileNameを使う。
FileName	LPCWSTR	inoptional	サイズを求めるソースファイル名(Unicode)。InfContext指定時はNULL可。
Section	LPCWSTR	inoptional	ファイルが属するコピーセクション名(Unicode)。NULL可。
FileSize	DWORD*	out	求めたファイルサイズを受け取る出力ポインタ。
RoundingFactor	DWORD	in	サイズを切り上げる丸め単位(バイト)。0で丸めなし。
